This high-density underlayment is engineered with a closed-cell Ethyl Vinyl Acetate (EVA) foam core integrated with a reflective silver foil membrane. The 2mm profile provides a stable, low-compression substrate that levels minor subfloor irregularities while acting as a high-performance thermal and vapor shield for floating floor systems.

Hydrophobic Vapor Protection: The integrated silver foil serves as a non-permeable moisture barrier, preventing capillary rise and protecting the floor covering from subfloor dampness and alkaline attack.
Thermal Regulation: Utilizing high-reflectivity technology, the metallic surface minimizes radiant heat loss, significantly enhancing the thermal resistance of the flooring assembly.
Structural Durability: The high-density EVA composition exhibits superior compressive strength and creep resistance, ensuring long-term thickness retention and joint protection under heavy mechanical loads.
Acoustical Damping: The elastomeric properties of the EVA core effectively attenuate impact sound transmission, improving the acoustic environment of multi-story structures.
Subfloor Compatibility: Suitable for application over concrete, plywood, and radiant heating systems, provided the surface is clean, dry, and structurally sound.
Installation Protocol: Material should be laid with the foil side facing upward; all seams must be butt-joined and sealed with moisture-resistant pressure-sensitive tape to maintain barrier integrity.
Compliance and Safety: Manufactured to meet international VOC emission standards, ensuring indoor air quality and compatibility with sustainable building certifications.
Chemical Stability: The inert EVA material is resistant to mold, mildew, and common household chemicals, ensuring biological stability throughout the product's lifecycle.
